CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 567,442, datedSeptember 8, 1896. Application led November 8, 1895. Renewed August l,1896. Serial No. 601,402. (No model.)

To a/ZZ whom, t 71cm/ concern:

Beit known that we, JAMES L. ASHLEY and WILLIAM E. MoDERMoTT, citizensof the United States, residing at Brookfield, in the county of Wahkiakumand State of Washington, have invented certain new and usefulImprovements in Can-Soldering Machines; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake an d use the same.

. Our invention relates to machines for soldering end seams of cans, andis of that class which comprises a molten-solder bath, a track, andcan-holders mounted on an endless chain which receive, automaticallyrotate, and carry the cans through the solder and discharge them fromthe machine. Our machine is a universal one. That is to say, it isequally as well adapted to solder oval as it is round cans.

The in vention will be hereinafter described, and particularly pointedout in the claims.

In the accompanying drawings, which form a part of This specification,Figure lis a front elevation of my invention. Fig. 2 is an end view ofthe same, parts being broken away. Fig. 3 is a side elevation lof thecarrier detached from the machine. Fig. 4 is a front elevation of thesame.

l represents the frame of the machine; 2, sprocket-wheels journaled insliding brackets or plates 3, said plates being mounted in slots 4,which are formed in the frame of the l machine.

shaft 8 is journaled a pinion 9.

is also journaled on the shaft 8.

l0 is a stud projecting laterally from one side of the carrier andprovided with two to spring l2, if desired, as Will be obvious to thoseskilled in mechanics Without further explanation.

l5 is a rack suitably secured to the frame of the machine.

16 is a small section of rack hinged to the main rack l5 at 17, theframe of the machine being cut away at 18, in which is secured a spring19 of suitable pattern, the section of rack I6 being normally in linewith'the rack 15.

2O is the bottom guide on which the can revolves.

21 is the solder-bath, and 22 is afront guide for the can which causes aslight friction overcoming a possible slip. Irregularities in the canare provided for by the spring 23, which is coiled around the rod 24,extending laterally from the guide 22, said rod being loosely secured instandards 25, which are secured on the bottom guide 20. An adjustablecollar is secured on the rod 24, against which one end of the spring 23is seated.

27 is a nut on the end of rod 24.

28 is the can.

The operation is as follows: The can, being introduced into the machine,is caught by the carrier and comes into contact with frictionroller '7,the spring l2 of the preceding carrier holding the can against saidroller. The belt 5 being started causes the carriers to move, the pinion9 engaging the rack from whence it takes its motion, whereby thefriction-roller is revolved in the same direction as that of thecarrier, thus revolving the can in the solder-bath. The front guide 22presses lightly against the can, thus causing aslight friction toovercome any possible slip. The spring 23 allows of movement of theguide 22, which might otherwise prevent thecan from rotating. The hingedrack 16, in connection with the spring 19, is used to adjust the cogsand obviate the possibility of jamming with the pinion 9.

What we claim, and desire to secure by Letl. In a can-soldering machineof the character described, a series of carriers, a friction# rollerjournaled in the lower end of each of said carriers, a tension-springsecured to the upper end of each of said carriers7 the tension-spring ofone carrier acting in conjunction with the friction-roller of thefollowing carrier.

2. In a can-soldering machine of the char-A acter described, a carrier,a rack, a second rack hinged to one end of said rack, a spring holdingthe hinged rack normally in line with the iirst-named rack, and meansconnecting said rack with the carrier.

3. In a can-soldering machine, a series of carriers, a frictionqollerjournaled in the lower end of each of the carriers, a tensionspringsecured 'ro the top of each of said carriers, a shaft extendinglaterally from said carriers, the tension-spring of one carrier actingin conjunction with the friction-roller of the following carrier, apinion journaled on said shaft, a rack adapted to be engaged by saidpinion and an endless belt, to which the carriers are secured, and meansto operate the same.'

4. In a can-soldering machine, an endless link belt, sprocket-wheelsadapted to engage said belt, a carrier having a friction-roller at itslowei1 end and a tension-spring secured to its upper end, a shaftextending laterally from said carrier, a pinion j ournaled on saidshaft, means securing the carrier to the endless belt, a rack, a secondrack hinged to the first-named rack, a spring holding said second racknormally in line with the first-n amed rack` a lower guide, asolder-bath, and a front guide consisting of a rail, rods secured tosaid rail and loosely mounted in suitable standards,a coiled spring andan adjustable collar onsaid rod, all combined and operating asdescribed.

In testimony whereof we affix our signatures in presence of twowitnesses.
